Specifications include, but are not limited to: THINNING SPECIFICATIONS
The desired treatment will include the thinning of ponderosa pine, cedar, and juniper up to 10” DBH to an average spacing of 25 feet between trees (trunks). To achieve the desired spacing and to promote forest health broken top, split top, and otherwise unhealthy trees, will be targeted first.
Treatment of spruce will result in scattered groups of 5 to 15 trees with approximately 25 feet of spacing between groups.
Stumps will be level cut flush to the ground.
All ponderosa pine 10 inches and under in diameter will be removed from, and within 25 feet of, stands of hardwood trees. Hardwood trees will not be cut unless they are a hazard or significantly damaged or are dead.
Dead standing snags should be removed to an average of 1 per acre.
Ponderosa pine, spruce, cedar, and juniper will be limbed to a minimum of 6 feet, not to exceed 1/3rd of the total tree height.
Felled trees and limbs (thinning slash) as well as other previously downed material will be removed, chipped, or piled.
Trees may be left as a privacy buffer within reason, and approved if approved by a SDWF representative.
Trees within a manicured lawn will not be included in the project.
Trees near structures or powerlines that require excessive costs, equipment, or time are not included in the project.
Existing handpiles must be removed, chipped, or burned.
Existing machine piles are not included in the scope of work unless authorized by SDWF.
Piles to be burned will between 6 and 8 feet in diameter, and between 5 and 7 feet in height.
Piles will not be constructed under the crown of any tree or on top of stumps.
Piles will be constructed away from powerlines/structures/other infrastructures.
Burning of piles will be conducted by the contractor as conditions allow and under SDWF burn permit guidelines:
Minimum of 2 inches of continuous snow cover.
All materials shall be pulled into the center for 100% minimum consumption.
Piles will be monitored for a minimum of 3 days after the last smoke is visible.
